Owing to the changes in postal rates, and the necessary alteration in colours of some Canadian stamps to conform to colour regulations established by the Universal Postal Union, the current 10-cent blue stamps were replaced by 10-cent stamps in light brown. The blue colour was needed for the 8-cent stamps.
When a sovereign accedes to the British throne, a new issue of postage stamps is necessary. Many practical reasons prevent the change being made at once. Post Office departments nearly always keep large stocks of stamps bearing the portrait of the late monarch. Considerations of respect to the memory of the deceased sovereign, and less sentimental motivations of expediency and economy, usually combine to require that these stamps should continue to circulate for many months, on some cases even a year or two before an issue portraying the new sovereign appears. The accession to the throne of His Majesty King George V on 6th May, 1910, necessitated the issue of a new series of postage stamps bearing the portrait of His Majesty. The denominations first issued were the same as those of the King Edward VII series of 1908, but the colours of the 10-cent and 50-cent denominations were different.
